Spatial-temporal changes in water transparency and its impact factors in Lake Wuliangsuhai
摘要
Abstract
The spatial distribution, temporal changes of water transparency and relationship between transparency and turbidity, suspended substance, chlorophyll-a, radio of total nitrogen and total phosphate, pH were analyzed based on monthly (May-October) monitoring data in Lake Wuliangsuhai from 2006 to 2008. The results indicated that the water transparency in Lake Wuliangsuhai in 2006 to 2008 ranged from 0.33m to 1.62m with a mean value of 0.93m, and the distribution trend of transparency took on increasing from the northeast to the southwest. The correlation analysis results showed that turbidity and the amount of suspended substances are two significant factors that affected the transparency. Their regression functions can be represented as SD=1.489x~(-0.471)(R=0.83, N=100, P<0.0001) and S~(1/4)=-3.948lnSD+12.055 (R=0.65, N=100, P<0.0001) respectively.关键词
